CFD Simulation of a Wetted-Wall Column for Natural Gas Sweetening Using DEA Solution
Natural gas usually contains significant amounts of acid gases when it is extracted from underground reservoirs. Therefore, it must be treated by appropriate processes to remove these acidic components. In this study, the simultaneous absorption of carbon dioxide and hydrogen sulfide from natural gas into diethanol amine solution was simulated using CFD. Absorption process was performed in a we...
متن کاملModeling and simulation of a wetted-wall column for SO2 absorption with aqueous ammonia solution
In a wetted-wall column of pilot-scale sulphur dioxide removal efficiencies were measured at 20 and atmospheric pressure with aqueous ammonia solutions. The liquid-phase mass transfer coefficient and gas-phase mass transfer coefficients of the system were determined. Based on the classical two-film theory the mathematical model was built to describe the complex absorption process. Combined with...
متن کاملWetting between parallel fibres; column-unduloid and column disintegration transitions.
Wetting phenomena are studied for a fibre bundle consisting of three parallel cylinders of radius b. Two types of long liquid column (a disintegrated and a channel-filling column) and a state akin to the unduloid can form, depending on whether the cylinder-cylinder separation, 2d, is larger or smaller than certain critical values. The dimensionless threshold values d/b have been calculated, whe...
متن کاملWetting of a symmetrical binary fluid mixture on a wall.
We study the wetting behavior of a symmetrical binary fluid below the demixing temperature at a nonselective attractive wall. Although it demixes in the bulk, a sufficiently thin liquid film remains mixed. On approaching liquid vapor coexistence, however, the thickness of the liquid film increases and it may demix and then wet the substrate. We show that the wetting properties are determined by...
متن کاملPreparation of Graphene-amine Nanofluid for Absorption of Carbon Dioxide (CO2) and Hydrogen Sulfide (H2S) from a Natural Gas Stream in a Wetted Wall Column
In this study, it was shown that how CO2 and H2S were removed from a natural gas stream, using a nanofluid containing nanoporous graphene in Diehanolamine (DEA). Before running the experiments, the appropriate values were chosen for the nanosheet dosage and the liquid and gas flow rates in the absorption experiments, which were performed in a laboratory scale wetted wall column. In the expe...
